svn commit: r210875 - head/sbin/hastd

[Pawel Jakub Dawidek]

New Revision: 210875
URL: http://svn.freebsd.org/changeset/base/210875

Log:
  Problem with assertion is that it logs on stderr. Add two macros:
  PJDLOG_ASSERT() and PJDLOG_VERIFY() that will check the given condition
  and log the problem where appropriate. The difference between those
  two is that PJDLOG_VERIFY() always work and PJDLOG_ASSERT() can be
  turned off by defining NDEBUG.
